Senior Mobile SDK Engineer

Location: LATAM (Remote)

The Senior Mobile SDK Engineer is responsible for designing, building, and maintaining high-performance mobile advertising SDKs for both iOS (Swift) and Android (Kotlin) platforms. The role focuses on developing scalable and production-ready SDKs that allow mobile applications to integrate advanced ad formats including native ads, rewarded video, and interstitial ads.

The engineer will own the mobile ad SDK architecture end-to-end, including SDK design, ad lifecycle management, measurement integration, and production monitoring. This includes implementing the full mobile advertising lifecyclesuch as ad request handling, ad rendering, impression tracking, click tracking, and conversion measurement while ensuring reliability and minimal performance impact on host applications.

A critical responsibility of the role is integrating the Open Measurement SDK (OMID) developed by the IAB Tech Lab, enabling standardized ad viewability and verification measurement. The engineer will work with industry verification vendors such as Moat, Integral Ad Science, and DoubleVerify to validate signals and resolve discrepancies in measurement.

The role also requires implementing privacy and consent frameworks including TCF v2.2, GPP, App Tracking Transparency (ATT), and COPPA compliance, ensuring that the SDK aligns with global privacy regulations.

Additionally, the engineer will be responsible for monitoring live ad traffic in production, ensuring measurement accuracy, signal integrity, and stable SDK performance across different mobile environments.

The SDKs must be distributed through industry-standard package systems such as CocoaPods or Swift Package Manager for iOS and Maven Central for Android, along with clear documentation to ensure seamless integration for publisher applications.
